Formatting difference on paste

Copying from website to Scrivener file. How do I stop the large black lines?

The Original:

After Paste.

Looks like some bad interaction between the website’s CSS and the text importer. Try using Edit/Paste and Match Style instead of standard paste—or if you need italic and bold ranges, just avoid copying those particular rules. Copy and paste the text inside them, then the rest.

Thank you, that was my decision. But I wished it would have imported with the bold because of the large number of separate posts.
